MOUNTING FOR FIRE DOORS AND SHUTTERS.

Specification of Letters Patent.

Patented June 5, 191?.

Application filed July 7, 1916 Serial N 0. 108,071.

To all whom it may concern:

Be it known that I, FELIX L. SAINo, a citizen of the United States, residing at Memphis, Shelby county, and State of Tennessee, have invented and discovered certain new and useful Improvements in Mountings for Fire Doors and Shutters, of which the following is a specification.

The present invention relates to mountings for fire-proof doors and shutters, and consists in the combinations and arrangements of parts hereinafter described and particularly set fortlr in the accompanying claim.

The invention has for its purpose to provide a hinge. mounting for sheet metal fireproof doors or shutters wherein the door or shutter may be set to swing freely regard less of the manner in which the side walls of the building have been constructed; and wherein the hinge may be adjusted for rectifying any inaccuracies that occur after the doors and shutters have been mounted.

The invention has for its further purpose to provide a hinge mounting that will afford a rigid support for the pivotal member, to the end that the weight of the door or shutter will not cause distortion thereof, and thereby avoid excessive friction between the pivotal member and the support- 1ng pin.

The invention is shown by way of illustration in the accompanying drawings, wherein Figure 1 is a perspective view of the hinge, and

Fig. 2 a central longitudinal sectional view thereof.

Referring to the construction in detail, the hinge consists of a plate 1, constructed with corrugations to fit the corrugated surface of the door for which this type of hinge is particularly adapted. Said plate is of substantially triangular form and has, at the apices thereof, elongated openings or slots 2 that receive the bolts for fastening the plate to the door or shutter. The portions of the plates immediately surrounding the slots are raised and corrugated, as at 3, to receive the corrugated surfaces of the washers that are fitted on the securing bolts (not shown), after the manner described in my co-pending application for United States Patent, bearing the Serial Number 30,611, and dated May 26, 1915.

The body of the plate 1 is formed with integral ,raised portions 1*, between which the plate is countersunk forming the pair of inset webs a and 5 that provide a recess to receive the hinge bar 6 that fits therein after the manner illustrated in Fig. 1. Said reoess forms a shoulder or abutment 7 against which the free end 8 of the bar 6 may contact, as in Fig. 2, and a bolt 9 passesthrough a slot 10 formed in said bar and the aperture 11 in the web 4 and secures said bar in set position.

A web 12 is formed integral with the raised portions 1 and immediately overlies the recess or socket that receives the bar 6 and forms an overlying structure for the bar and rigidly holds the latter against distortion due to the weight of the door or shutter.

It is obvious that those skilled in the art may vary the details of construction and arrangement of parts without departing from the spirit of my invention, and therefore I do not wish to be limited to such features except as may be required by the claim.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:

A hinge for mounting corrugated doors or shutters comprising a corrugated plate adapted to be adjustably secured on the door or shutter, said plate constructed with integral raised portions and the plate between said raised portions formed with a pair of inset web portions providing a recess, a web portion connecting said raised side portions and overlying one of said webs and forming a socket therewith and leaving the other of said webs uncovered, a member adjustably fitting within said socket, and means for securing said member to the uncovered web portion, substantially as set forth.

In witness whereof, I have hereunto set my hand and seal at Memphis, Tennessee, this 4th day of July, A. D. nineteen hundred and sixteen.
